- no space is allowed between ',' and the operator.
- The operator can be one of:
| + | add |
| - | subtract |
| * | multiply |
| / | divide |
| < | less |
| <= | less or equal |
| > | greater |
| >= | greater or equal |
| = | equal |
| == | equal |
| != | not equal |
| << | bit shift left / up |
| >> | bit shift right / down |
| && | logical AND (return 1 if True, 0 if False) |
| || | logical or (return 1 if True, 0 if False) |
| & | bitwise and |
| | | bitwise or |
| ! | logical not of second operand |
| ^ | bitwise xor |
- integers are 32 bit internally
- the codes for the different operations are taken from the C programming language.
Example
%op(%1.phy,+,1) - adds one to the physical number of the event owner. Which can be used to send a message to the next station, and creating a chain of events over all stations.
